PMDG 747 FMC waipont latt/long

I am getting really frustrated with the waypoint prohramming of the FMC useing lattitude/longatude codes.

I have read the manual on this but it only breifly covers and gives one example.

I did get some waypoints going on the 737 but the 747 is a little strage..

I am trying to make my OWN flight from EGLL - KJFK

N51°27'12.13
W0°58'08.77

N52°28'49.61
W1°54'12.28
